PRT File Converter
We can't convert CAD Part (PRT) files — here's what does work.
Why PRT can't be converted here
PRT is Creo / Siemens NX's own closed format. Its internal structure is proprietary, so no open-source library can read it — which is why no converter outside Creo / Siemens NX can open your file.
What does work: open the file in Creo / Siemens NX and export it as STEP. We convert STEP reliably.

The .prt extension is used by several parametric CAD systems (such as Creo/Pro-ENGINEER and NX) for a single part file; the internal structure is proprietary and version-specific to whichever CAD system created it.
